Tornado Shelter Door Comparison
Your shelter door is the most important thing to protecting you from a tornado. Many shelter doors are manufactured and developed by companies with limited design experience. Many of these companies only build storm shelters, work seasonally or depend on outside sources to manufacture critical parts. While they may advertise they have "been in existence for years" some manufacturers close their doors as soon as the tornado season is over, thus creating a high turnover of inexperienced laborers. Sometimes the customer is left with no available manufacturer or customer service support for months to come, until tornado season fires back up. These fly by night operations typically build low end, lowest priced, low quality, low volume products. These units feature inferior materials with poor design, tooling or construction. Take a moment to research the design of a tornado shelter or storm shelter before your purchase. Paying special attention to the door ask yourself is the design as safe as it could be? Does the manufacturer offer a lifetime warranty? Does the door have a lifetime warranty? Is the door warranted against rust, mold or rotting? Not all storm shelter doors are created equal! Watch the Professor Puppet in the video below to learn the differences between Storm Shelter doors and their respective materials.

Just as with the shelter bodies there are a number of issues with specific materials on tornado shelter doors. Steel doors for example are often extremely heavy and very cumbersome to operate. While initially, they meet or exceed FEMA debris impact standards, it is unknown how the doors will hold up once they begin to rust in the field. It is also possible for internally mounted shocks to become missiles or flying projectiles if the door is impacted. Is my door secure? Could my door rot or rust all the way thru making it unsafe? How badly will the UV damage the material construction? Don't subject yourself to these worries! Granger is the only world class manufacturing entity to have successfully designed and tested (3) different doors to meet or exceed FEMA 320 specifications & standards. All of Granger's doors have been tested at Texas Tech Wind Science & engineering Research Center. The current door of the Granger ISS exceeded both FEMA 320 and FEMA 361 testing standards with only one door used! Can any other shelter door manufacturer state that?
